d`To att whom. it may concern Be it known that I, WXLLIAM J. HAMIL- Tos, a subjectnf the King of England, re-

ing drawings.

the motor for 'cooling the EIO ' to form between. them rectan Flintiin-the county of Genesee and siding at h Michigan, have invented. certaln State of new and useful' Improvements in Radiators',

oi' which the following is a specification, reference being had therein to the accompanylj This invention relates to improvements in radiators espe'eiallycadapted vvfor use upon motor vehicles for cooling the waterwbicb is circulated through Vthe `water jacket of I same.

The object of the inven a simple,` cheap and' efficient construction yof cooling core for sucha radiator which'wi'll give to the radiator an attractive appearance and be eiiicien't 'in operation.

To these ends the invention consists in the matters hereinafter set forth and -more particularly ointed out in the claims reference being ad'tothe accompanying draw#v ing in which 5 Figure 1 is a front. elevationl of a device embodying the invention; FigfQ isfanl enlarged vertical"sectionfthrough a portion of the core of "the radiator; andfFlg. 3 ,is a horizontal section of'f'the saineon thef line III-UI of Fig. 2.

Radiators'embodying this invention may he made in any 'desired' form or size and consist of a top 'tank`A and "bottom tank B and a core C vbetween saidtanks forming a .plurality of water "passages the Atanks'wbich'passages'ai'e soshaped as sages 2 extendingtlirol'rghl -tecore from front to: rear'I thereof for the free passage of air therethrough,the saine 'passing-in, 'contact withy the water "passagesasit `'passes through the-air rpasshgtges"thereby reducing the temperature yoi thawater. Each water passage 1 is formed by two thin sheetv 4metal plates which are spaced a short distance apart to form 'the water passage between them, by ovelappngendflanges 3 which are soldered together 'to-make a tight' joint, In overlapping 'the end fianges' 3,should there be'an excess of-meta edges thereof, the excessive meta-l can be sheared or buckled without interfering with the general construction of the radiator. To solder the end flanges 3, the same can be dipped in solder whereby the solder will co- 'tending sage and `folded upon tion is toprovide i erally extending continuations 9 of thehori'- l connecting.

-cooling attbe lateral l extension when closing the front' andi-'ear "cooled and heavy enough* to force its operate with thewalls of 'flanges in forming a tight joint.

The parallel plates 4 and,

5 forming each waterpassage are so bent las to form a tortuous passage having;l right angle bends, the same forming alternate straight vertical portions 6 connected by straight. horizontal portions 7 and thevplate 4 forming one side of the ypassage being bent laterally andtold'ed upon itself` opposite one end of each alternatehorizontal pori tion ofA the passage tofform a laterally exportions, and the plate 5 bengfbent'ilaterally 1n an oppositefdirection from/the pasitself. to form latzontal portions of the passage which alternate kwith thoserhaving [extensions 8 formed bythe platel 4.

l A pluralitl :ofthe watertubesor passages formed by tlie'platesl and 5 as described, are assembled to form the core 'of't-he radiator'by placing said .tubes sidejby side with their horizontally extending portions ,in

alineinent and thelateralextensions 8 'of one Vtube, abutting the'upper ends ofthe vertical portions of the next adjacent tube and the laterall i extending` adjacent tu alternatlng with the portions 9 and 'abutting the' u per -ends ofthe verticalportions of said' rst named tube. The assemblage thus forms lthe rectangular air passagesv 2 openy at their endsthrough'. the front and `rear faces of the core.` Tubes fashioned as described Vmay.be'accurately and expeditiously continuation 8 of said horizontalv portions Q of said madel `by means ofv diesk which will-formeachplate ,off the.tube-into 'shape and these plateszmay ythenqbe placed es soldered to form togetherI and their ,ed

ywa along the horizontal portions `toniingle with the warmer stream and thereby cool ythe-en. tire body. The angular'y form of thetubes solderedl vrati," their meeting points to fornirthecomplete lcore. The upper and lower los when assembled gives to the core-the appear ance of being toi-med of a plurahty of rec- ,V d ing assembled side by side' with the laterally 36 extending portions on one tube in abutting engagement with the vertical portions on the 'nektv adjacent t-ube,- said horizontally and' lalerallyi.extendingipoitions of the several tubes being arranged in horizontal aline- 35 nlent across the core.
